tundish cover(【技】中间包覆盖剂:加人到中间包内钢水面上的保护渣,其主要功能是:隔离钢水和空气,减轻钢水的二次氧化;吸收从钢水中分离出来的非金属夹杂物;保持钢水的热量,减少温度损失以及在较长时间使用后仍能保持性能稳定。: Resin-bonded magnesia dams and weirs were used at both casters to improve steel flow in tundish and ensure that the steel was brought into sufficient contact with the tundish cover. 将树脂结合的镁质坝堰用于这两台连铸机,从而改善了中间包内的钢水流动,保证了钢水与中间包覆盖剂充分接触。)
deoxidizer(【技】脱氧使用的材料。向钢水中加人对氧的亲和力比铁大的元素,与氧生成不溶于钢水的氧化物或复合氧化物,然后将其从钢水中排除。常用的块状脱氧剂有硅铁、锰铁、铝、硅锰合金等。粉状脱氧剂有炭粉、硅铁粉、硅钙粉等。: Aluminum is most extensively used as a deoxidizer of molten steel. 铝作为钢水的脱氧剂得到了十分广泛的应用。)
desiliconization agent(【技】在铁水预处理工艺中,为实现铁水预脱硅而向铁水中添加的各种添加剂。脱硅剂通常由氧化剂、成渣剂及助熔剂组成。: Desiliconization of hot metal is carried out by using main desiliconization agents such as oxygen, mill scale, sinter fines, and iron/manganese ore fines. 铁水进行脱硅所使用的主要脱硅剂如氧气、轧钢皮、烧结矿粉以及铁锰矿粉等。)
amount of flux to be added(The static charge model can calculate the amount of oxygen to be blown and the amount of fluxes to be added to attain the desired (aim) carbon and temperature for the heat. 为了取得该炉次的目标碳和目标温度,静态装料模型可以计算出需要的吹氧量和待加的熔剂量。)
